What’s the best way to optimize our website to prevent crashes?

you have emailed my to ask me to update my card using the "payment methods" section, but this section does not exist, and there is no way I can put in my new card details.

Use passwordless or MFA on all service.

Strong passwords are key when it comes to internet service.

Many password resets information is sent to an email address. Access to such critical account should be protected with either passwordless or MFA functionality. A hacked email account with username and password is a golden ticket to steal the identity of customer/user.

If a script run via cron begin returning error at every run, it would be useful to auto suspend that to avoid being flooded by mails.

The feature for the removal of the forwarded emails' copies have been implemented on Linux. It is needed to have the same possibility on Windows as well.

Instead of or in addition to Phusion Passenger add PM2

PM2 has more Github Stars and a larger following.

Add an ability to delete backups via CLI using the pleskbackup utility

Mailgroups currently simply forward mail to all its members. When forwarding, spam rules do not apply. Hence the black/whitelist settings are also ignored.

At least we should be able to only allow mailgroups to be used from internal accounts, so that mailgroups are not an easy target for spammers.

Suggest adding the CLI commands for enabling "Keep websites secured" and all four options:
"Include the "www" subdomain"
"Secure domain aliases"
"Secure webmail"
"Secure mail"
in SSL/TLS certificates.
It would enhance the advanced administration of SSL certificates, especially beneficial on servers with large amount of domains.

In some cases, it is required to change/manage settings in Watchdog (for example Preferences in Watchdog) for a great number of servers. For now, it is possible only from Plesk GUI which in the scope of about 100 servers will become a great deal to do. So it would be much convenient to be able to manage these settings with command through CLI.

Hello,

It would be very convenient to have a watchdog support in Ubuntu 20

Please allow selecting specific mailboxes for transferring with Plesk Migrator

Possibility to edit the DKIM popup message which contains the TXT records that need be added on external DNS server.

3rd step.

Add support for pre configured JIT compiler / support for managing configurations via Plesk.

Add support to at least extract xz and bzip2 compressed tar archives. Currently I can only extract gzip compressed archives and it's a pain every time I want to upload and extract a xz or bzip2 archive. It shouldn't be much work to implement, since the tar command can do this transparently without adding extra switches, it can detect the format automatically.
Also, having the ability to compress to any tar format would be nice.

Imagine being able to perform actual maintenance, when "maintenance mode" is engaged... Instead, actual maintenance can only be done with a 3rd party extension. Or, consider changing the labeling of "maintenance mode" to "WordPress On/Off" since engaging maintenance mode prevents actual maintenance, prevents logging in, and just shuts down the site.

When you click the button to pull updates, when its done the button just lights back up so you can click on it again but no notification is done to let you know the pull is complete. It would be nice to have something show up at the top to say the pull is complete and then the box with the last pull information updated to the latest pull info. Essentially refresh the page with a notification at the top that the pull was successful.

We would appreciate it if the setting of the time were included in addition to the days for the «automatic replies» by e-mail. For part-time employees, this attitude would be a real asset.

Since Plesk Obsidian 18.0.38, the Domains menu has been updated and the icons have been replaced with black-and-white design.

Please bring back the colored icons or add an option to switch between the old and new style.
